 # Core Engine
 
-The **Core Engine** is the foundation of the Provisioning platform—a modular, high-performance infrastructure automation system built on **Nushell** and **KCL**. It provides unified CLI tools, core libraries, and extensible architecture for managing cloud infrastructure, Kubernetes clusters, and infrastructure-as-code workflows.
+The **Core Engine** is the foundational component of the [Provisioning project](PRIOVISIONING.md), providing the unified CLI interface, core Nushell libraries, and essential utility scripts. Built on **Nushell** and **KCL**, it serves as the primary entry point for all infrastructure operations.
 
 ## Overview
 
-The Core Engine serves as the central orchestration layer, providing:
+The Core Engine provides:
 
-- **Unified CLI Interface** - Single command-line interface for all infrastructure operations
+- **Unified CLI Interface** - Single command-line tool for all infrastructure operations
-- **Core Libraries** - Reusable Nushell modules for configuration, validation, deployment, and workflow management
+- **Core Libraries** - Reusable Nushell modules for configuration, validation, and utilities
 - **Provider Abstraction** - Cloud-agnostic interface supporting UpCloud, AWS, and local providers
-- **Workflow Orchestration** - Batch operations, dependency resolution, and state management
+- **Workflow Integration** - Commands for submitting and managing workflows (executed by the orchestrator)
 - **Configuration System** - Hierarchical, config-driven architecture with 476+ configuration accessors

+**Implementation Date**: 2025-10-06
+**Version**: 1.0.0
+**Status**: ✅ Complete - Ready for Testing
+
+---
+
+## Executive Summary
+
+A comprehensive service management system has been implemented for orchestrating platform services (orchestrator, control-center, CoreDNS, Gitea, OCI registry, MCP server, API gateway). The system provides unified lifecycle management, automatic dependency resolution, health monitoring, and pre-flight validation.
+
+**Key Achievement**: Complete service orchestration framework with 7 platform services, 5 deployment modes, 4 health check types, and automatic dependency resolution.
+
+---

+2. **control-center** - Web UI (binary, depends on orchestrator, order: 20)
+3. **coredns** - Local DNS (Docker, conflicts with dnsmasq, order: 15)
+4. **gitea** - Git server (Docker, order: 30)
+5. **oci-registry** - Container registry (Docker, order: 25)
+6. **mcp-server** - MCP server (binary, depends on orchestrator, order: 40)
+7. **api-gateway** - API gateway (binary, depends on orchestrator, order: 45)
+
+**Configuration Features**:
+- Complete deployment specifications

+## Usage Examples
+
+### Start Platform
+
+```bash
+# Start all auto-start services
+provisioning platform start
+
+# Start specific services with dependencies
+provisioning platform start control-center
+
+# Check platform status
+provisioning platform status
+
+# Check platform health
+provisioning platform health
+```
+
+### Manage Individual Services
+
+```bash
+# List all services
+provisioning services list
+
+# Start service (with pre-flight checks)
+provisioning services start orchestrator
+
+# Check service health
+provisioning services health orchestrator
+
+# View service logs
+provisioning services logs orchestrator --follow
+
+# Stop service (with dependent check)
+provisioning services stop orchestrator
+```
+
+### Dependency Management
+
+```bash
+# View dependency graph
+provisioning services dependencies
+
+# View specific service dependencies
+provisioning services dependencies control-center
+
+# Check if service can be stopped safely
+nu -c "use lib_provisioning/services/mod.nu *; can-stop-service orchestrator"
+```
+
+### Health Monitoring
+
+```bash
+# Continuous health monitoring
+provisioning services monitor orchestrator --interval 30
+
+# One-time health check
+provisioning services health orchestrator
+```
+
+### Validation
+
+```bash
+# Validate all services
+provisioning services validate
+
+# Check readiness
+provisioning services readiness
+
+# Check required services for operation
+provisioning services check server
+```
+
+---
+
+## Integration Points
+
+### 1. Command Dispatcher
+
+Pre-flight checks integrated into dispatcher:
+
+```nushell
+# Before executing operation, check required services
+let preflight = (check-required-services $task)
+
+if not $preflight.all_running {
+    if $preflight.can_auto_start {
+        auto-start-required-services $task
+    } else {
+        error "Required services not running"
+    }
+}
+```
+
+### 2. Workflow System
+
+Orchestrator automatically starts when workflows are submitted:
+
+```bash
+provisioning workflow submit my-workflow
+# Orchestrator auto-starts if not running
+```
+
+### 3. Test Environments
+
+Orchestrator required for test environment operations:
+
+```bash
+provisioning test quick kubernetes
+# Orchestrator auto-starts if needed
+```

+```
+
+### 💬 **Chat Examples**
+
+**User:** *"I need to set up a scalable web application infrastructure"*
+
+**AI:** *"I can help you design a scalable web infrastructure! Let me generate a configuration that includes:*
+
+*- Load balancers for high availability*
+*- Auto-scaling application servers*
+*- Database with read replicas*
+*- Caching layer*
+*- CDN for static assets*
+
+*Would you like me to create this for a specific provider like AWS, UpCloud, or local deployment?"*
+
+**User:** *"Generate it for UpCloud with monitoring included"*
+
+**AI:** *"Perfect! I'll generate an UpCloud configuration with monitoring. Here's your infrastructure setup:*
+
+```kcl
+import upcloud_prov
+servers = [
+   // Load balancer
+   upcloud_prov.Server_upcloud {
+      hostname = "lb-01"
+      plan = "2xCPU-4GB"
+      // ... configuration
+   }
+   // Application servers with auto-scaling
+   // Database servers with replication  
+   // Monitoring stack with Prometheus/Grafana
+]
+```
+
+*This configuration includes 7 servers optimized for high availability and performance. Would you like me to explain any specific part or generate additional configurations?"*
+
+### 🚀 **Advanced Features**
+
+#### Interactive Configuration Builder
+```bash
+./provisioning ai generate --interactive
+```
+
+This launches an interactive session that asks specific questions to build optimal configurations:
+
+1. **Infrastructure Purpose** - Web app, data processing, ML training, etc.
+2. **Scale Requirements** - Number of users, traffic patterns, growth projections
+3. **Provider Preference** - Cloud provider selection and regions
+4. **Service Requirements** - Databases, caching, storage, monitoring
+5. **Security Needs** - Compliance requirements, network isolation
+6. **Budget Constraints** - Cost optimization preferences
+
+#### Configuration Optimization
+```bash
+# Analyze and improve existing configurations
+./provisioning ai improve existing_config.k --output optimized_config.k
+
+# Get AI suggestions for performance improvements
+./provisioning ai query --prompt "How can I optimize this configuration for better performance?" --context file:servers.k
+```
+
+## Integration with Existing Workflows
+
+### 🔄 **Workflow Integration**
+
+1. **Generate** configurations with AI
+2. **Validate** using KCL compiler
+3. **Review** and customize as needed  
+4. **Apply** using provisioning commands
+5. **Monitor** and iterate
+
+```bash
+# Complete workflow example
+./provisioning generate-ai servers "Production Kubernetes cluster" --validate --output servers.k
+./provisioning server create --check  # Review before creation
+./provisioning server create          # Actually create infrastructure
+```
+
+### 🛡️ **Security & Best Practices**
+
+- **API Keys**: Store in environment variables, never in code
+- **Validation**: Always validate AI-generated configurations
+- **Review**: Human review recommended for production deployments
+- **Version Control**: Track all generated configurations
+- **Testing**: Use `--check` mode for dry runs
+
+### 🧪 **Testing & Development**

+# Extension System Quick Start Guide
+
+Get started with the Extension Loading System in 5 minutes.
+
+## Prerequisites
+
+1. **OCI Registry** (optional, for OCI features):
+   ```bash
+   # Start local registry
+   docker run -d -p 5000:5000 --name registry registry:2
+   ```
+
+2. **Nushell 0.107+**:
+   ```bash
+   nu --version
+   ```
+
+## Quick Start
+
+### 1. Load an Extension
+
+```bash
+# Load latest from auto-detected source
+provisioning ext load kubernetes
+
+# Load specific version
+provisioning ext load kubernetes --version 1.28.0
+
+# Load from specific source
+provisioning ext load redis --source oci
+```
+
+### 2. Search for Extensions
+
+```bash
+# Search all sources
+provisioning ext search kube
+
+# Search OCI registry
+provisioning ext search postgres --source oci
+```
+
+### 3. List Available Extensions
+
+```bash
+# List all
+provisioning ext list
+
+# Filter by type
+provisioning ext list --type taskserv
+
+# JSON format
+provisioning ext list --format json
+```
+
+### 4. Manage Cache
+
+```bash
+# Show cache stats
+provisioning ext cache stats
+
+# List cached
+provisioning ext cache list
+
+# Clear cache
+provisioning ext cache clear --all
+```
+
+### 5. Publish an Extension
+
+```bash
+# Create extension
+mkdir -p my-extension/{kcl,scripts}
+
+# Create manifest
+cat > my-extension/extension.yaml <<EOF
+extension:
+  name: my-extension
+  version: 1.0.0
+  type: taskserv
+  description: My awesome extension
+EOF
+
+# Publish to OCI
+provisioning ext publish ./my-extension --version 1.0.0
+```
+
+## Configuration
+
+### Enable OCI Registry
+
+Edit `workspace/config/local-overrides.toml`:
+
+```toml
+[oci]
+registry = "localhost:5000"
+namespace = "provisioning-extensions"
+auth_token_path = "~/.provisioning/oci-token"
+
+[extensions]
+source_type = "auto"  # auto, oci, gitea, local
+```
+
+### Test OCI Connection
+
+```bash
+provisioning ext test-oci
+```
+
+## Common Workflows
+
+### Workflow 1: Install Taskserv from OCI
+
+```bash
+# Search for taskserv
+provisioning ext search kubernetes --source oci
+
+# Load it
+provisioning ext load kubernetes --version ^1.28.0
+
+# Use in provisioning
+provisioning taskserv create kubernetes
+```
+
+### Workflow 2: Develop and Test Locally
+
+```bash
+# Copy to local path
+cp -r my-extension ~/.provisioning-extensions/taskservs/
+
+# Load locally
+provisioning ext load my-extension --source local
+
+# Test
+provisioning taskserv create my-extension --check
+
+# Publish when ready
+provisioning ext publish ./my-extension --version 1.0.0
+```
+
+### Workflow 3: Offline Usage
+
+```bash
+# Pull extensions to cache while online
+provisioning ext pull kubernetes --version 1.28.0
+provisioning ext pull redis --version 7.0.0
+provisioning ext pull postgres --version 15.0.0
+
+# Work offline - uses cache
+provisioning ext load kubernetes
+provisioning ext load redis
+```
+
+## Extension Structure
+
+Minimal extension:
+
+```
+my-extension/
+├── extension.yaml       # Required manifest
+└── kcl/                # At least one content dir
+    └── my-extension.k
+```
+
+Complete extension:
+
+```
+my-extension/
+├── extension.yaml       # Manifest
+├── kcl/                # KCL schemas
+│   ├── my-extension.k
+│   └── kcl.mod
+├── scripts/            # Installation scripts
+│   ├── install.nu
+│   └── uninstall.nu
+├── templates/          # Config templates
+│   └── config.yaml.j2
+└── docs/              # Documentation
+    └── README.md
+```
+
+## Troubleshooting
+
+### Extension Not Found
+
+```bash
+# Discover available extensions
+provisioning ext discover
+
+# Search by name
+provisioning ext search <name>
+
+# Check specific source
+provisioning ext list --source oci
+```
+
+### OCI Registry Issues
+
+```bash
+# Test connection
+provisioning ext test-oci
+
+# Check registry is running
+curl http://localhost:5000/v2/
+
+# View OCI config
+provisioning env | grep OCI
+```
+
+### Cache Problems
+
+```bash
+# Clear and rebuild
+provisioning ext cache clear --all
+
+# Pull fresh copy
+provisioning ext pull <name> --force
+```

+# Extension Loading System
+
+**Version**: 1.0.0
+**Status**: Implemented
+**Date**: 2025-10-06
+
+## Overview
+
+A comprehensive extension loading mechanism with OCI registry support, lazy loading, caching, and version resolution. Supports loading extensions from multiple sources: OCI registries, Gitea repositories, and local filesystems.
+
+## Architecture
+

+```
+
+## Features
+
+### 1. Multi-Source Support
+
+Load extensions from:
+- **OCI Registry**: Container artifact registry (localhost:5000 by default)
+- **Gitea**: Git repository hosting (planned)
+- **Local**: Filesystem paths
+
+### 2. Lazy Loading
+
+Extensions are loaded on-demand:
+1. Check if already in memory → return
+2. Check cache → load from cache
+3. Determine source (auto-detect or explicit)
+4. Download from source
+5. Cache locally
+6. Load into memory
+
+### 3. OCI Registry Integration
+
+Full OCI artifact support:
+- Pull artifacts with authentication
+- Push extensions to registry
+- List and search artifacts
+- Version tag management
+- Manifest metadata extraction
+
+### 4. Caching System
+
+Intelligent local caching:
+- Cache directory: `~/.provisioning/cache/extensions/{type}/{name}/{version}/`
+- Cache index: JSON-based index for fast lookups
+- Automatic pruning: Remove old cached versions
+- Statistics: Track cache size and usage
+
+### 5. Version Resolution
+
+Semver-compliant version resolution:
+- **Exact**: `1.2.3` → exactly version 1.2.3
+- **Caret**: `^1.2.0` → >=1.2.0 <2.0.0 (compatible)
+- **Tilde**: `~1.2.0` → >=1.2.0 <1.3.0 (approximately)
+- **Range**: `1.2.0-1.5.0` → between versions
+- **Latest**: `*` or `latest` → highest version
+
+### 6. Discovery & Search
+
+Multi-source extension discovery:
+- Discover all extensions across sources
+- Search by name or type
+- Filter by extension type (provider, taskserv, cluster)
+- Get available versions

+
+## Integration Examples
+
+### Example 1: Load Taskserv from OCI
+
+```nushell
+use lib_provisioning/extensions/loader_oci.nu load-extension
+
+let result = (load-extension "taskserv" "kubernetes" "^1.28.0" --source-type "oci")
+
+if $result.success {
+    print $"Loaded kubernetes:($result.version) from ($result.source)"
+} else {
+    print $"Failed: ($result.error)"
+}
+```
+
+### Example 2: Discover and Cache All Extensions
+
+```nushell
+use lib_provisioning/extensions/discovery.nu discover-all-extensions
+use lib_provisioning/extensions/loader_oci.nu load-extension
+
+let extensions = (discover-all-extensions --include-oci)
+
+for ext in $extensions {
+    print $"Caching ($ext.name):($ext.latest)..."
+    load-extension $ext.type $ext.name $ext.latest
+}
+```
+
+### Example 3: Version Resolution
+
+```nushell
+use lib_provisioning/extensions/versions.nu resolve-oci-version
+
+let version = (resolve-oci-version "taskserv" "kubernetes" "^1.28.0")
+print $"Resolved to: ($version)"
+```
+
+## Troubleshooting
+
+### OCI Registry Not Reachable
+
+```bash
+# Test connection
+provisioning ext test-oci
+
+# Check config
+provisioning env | grep OCI
+
+# Verify registry is running
+curl http://localhost:5000/v2/
+```
+
+### Extension Not Found
+
+```bash
+# Search all sources
+provisioning ext search <name>
+
+# Check specific source
+provisioning ext list --source oci
+provisioning ext list --source local
+
+# Discover with refresh
+provisioning ext discover --refresh
+```
+
+### Cache Issues
+
+```bash
+# Check cache stats
+provisioning ext cache stats
+
+# Clear and rebuild
+provisioning ext cache clear --all
+
+# Prune old entries
+provisioning ext cache prune --days 7
+```
+
+### Version Resolution Issues
+
+```bash
+# Check available versions
+provisioning ext versions <extension-name>
+
+# Try explicit version
+provisioning ext load <name> --version 1.2.3
+
+# Force reload
+provisioning ext load <name> --force
+```
+
+## Performance Considerations
+
+- **Lazy Loading**: Extensions loaded on-demand, not at startup
+- **Caching**: Downloaded artifacts cached locally for fast access
+- **Parallel Discovery**: Multiple sources discovered concurrently
+- **Index-Based Lookup**: Cache index for O(1) lookups
+
+## Security
+
+- **Token-Based Auth**: OCI registry authentication via tokens
+- **Manifest Validation**: Extension structure validated before loading
+- **Permission Checks**: Extension permission policies enforced
+- **Secure Defaults**: HTTPS for registries (HTTP only for localhost)
+
+## Future Enhancements
+
+- [ ] Gitea source implementation
+- [ ] Digital signature verification
+- [ ] Multi-registry support
+- [ ] Extension dependency resolution
+- [ ] Automatic updates
+- [ ] Extension sandboxing
+- [ ] WebAssembly extensions
+- [ ] Extension marketplace UI

+
+## Usage Examples
+
+### Basic Workflow
+
+```bash
+# 1. Start Gitea
+provisioning gitea start
+
+# 2. Initialize workspace with git
+provisioning workspace init my-workspace --git --remote gitea
+
+# 3. Acquire lock
+provisioning gitea lock acquire my-workspace write --operation "Deploy servers"
+
+# 4. Make changes
+cd workspace_my-workspace
+# ... edit configs ...
+
+# 5. Push changes
+provisioning workspace push --message "Updated server configs"
+
+# 6. Release lock
+provisioning gitea lock release my-workspace 42
+```
+
+### Extension Publishing
+
+```bash
+# Publish taskserv
+provisioning gitea extension publish \
+    ./extensions/taskservs/database/postgres \
+    1.2.0 \
+    --release-notes "Added connection pooling"
+
+# Download extension
+provisioning gitea extension download postgres 1.2.0
+```
+
+### Collaboration
+
+```bash
+# Developer 1: Clone workspace
+provisioning workspace clone workspaces/production ./prod-workspace
+
+# Developer 2: Check locks before changes
+provisioning gitea lock list production
+
+# Developer 2: Acquire lock if free
+provisioning gitea lock acquire production write
+```
+
+---
+
+## Testing
+
+### Run Tests
+
+```bash
+# All tests (requires running Gitea)
+nu provisioning/core/nulib/tests/test_gitea.nu run-all-tests
+
+# Unit tests only (no integration)
+nu provisioning/core/nulib/tests/test_gitea.nu run-all-tests --skip-integration
+```
+
+### Test Coverage
+
+- ✅ API client operations
+- ✅ Repository CRUD
+- ✅ Release management
+- ✅ Issue operations (locking)
+- ✅ Workspace locking logic
+- ✅ Service management
+- ✅ Git operations (mock)
+- ✅ Extension validation (mock)
+
+---
+
+## Next Steps
+
+### Recommended Enhancements
+
+1. **Webhooks Integration**
+   - Implement webhook handlers
+   - Automated workflows on git events
+   - CI/CD integration
+
+2. **Advanced Locking**
+   - Lock priority system
+   - Lock queuing
+   - Lock notifications
+
+3. **Extension Marketplace**
+   - Web UI for browsing extensions
+   - Extension ratings/reviews
+   - Dependency resolution
+
+4. **Workspace Templates**
+   - Template repository system
+   - Workspace scaffolding
+   - Best practices templates
+
+5. **Collaboration Features**
+   - Pull request workflows
+   - Code review integration
+   - Team management
+
+---
+
+## Known Limitations
+
+1. **Comment API**: Gitea basic API doesn't support adding comments to issues directly
+2. **SSH Keys**: SSH key management not yet implemented
+3. **Webhooks**: Webhook creation supported in schema but not automated
+4. **Binary Deployment**: Process management for binary mode is basic
+
+---
+
+## Security Considerations
+
+1. **Token Storage**: Always use SOPS encryption for tokens
+2. **Repository Privacy**: Default to private repositories
+3. **Lock Validation**: Validate lock ownership before release
+4. **Token Rotation**: Implement regular token rotation
+5. **Audit Logging**: All lock operations are tracked via issues
+
+---
+
+## Performance Notes
+
+1. **API Rate Limiting**: Gitea has rate limits, batch operations may need throttling
+2. **Large Files**: Git LFS not yet integrated for large workspace files
+3. **Lock Cleanup**: Run cleanup periodically to prevent issue buildup
+4. **Docker Resources**: Monitor container resources for local deployments
+
+---
+
+## Conclusion
+
+The Gitea integration is **complete and production-ready** with:
+
+- ✅ 95+ functions across 6 modules
+- ✅ 13 KCL schemas for configuration
+- ✅ 30+ CLI commands
+- ✅ Comprehensive testing suite
+- ✅ Complete documentation (650+ lines)
+- ✅ Docker and binary deployment support
+- ✅ Workspace git integration
+- ✅ Distributed locking mechanism
+- ✅ Extension publishing workflow
+
+The implementation follows all PAP principles:
+- Configuration-driven (KCL schemas)
+- Modular architecture (6 focused modules)
+- Idiomatic Nushell (explicit types, pure functions)
+- Comprehensive documentation
+- Extensive testing
+
